The effectiveness of argon laser irradiation of pumiced and etched enamel on decalcification during orthodontic treatment: an in vivo study

ABSTRACT Objectives: The aim of this in vivo study was to investigate the preventive effect of two different adhesives on enamel demineralization and compare these adhesives with a conventional one. Materials and Methods: Fifteen patients requiring the extraction of their first four premolars for orthodontic treatment were included in the study. One premolar was randomly selected, and an antibacterial monomer-containing and fluoride-releasing adhesive (Clearfil Protect Bond, Kuraray Medical, Okayama, Japan) was used for orthodontic bracket bonding. Another premolar was randomly selected, and a fluoride-releasing and recharging orthodontic adhesive (Opal Seal, Ultradent Products, South Jordan, Utah) was used. One premolar was assigned as a control, and a conventional adhesive (Transbond XT, 3M Unitek, Monrovia, Calif) was used. The teeth were extracted after 8 weeks, and the demineralization areas of the 45 extracted teeth were analyzed using microcomputed tomography with software. Results: There was no significant difference between the white spot lesion (WSL) rates of the adhesives (P > .05). The volumes of the WSLs varied from 0 to 0.019349 mm3. Although Opal Seal showed the smallest lesion volumes, there was no significant difference in volumetric measurements of the lesions among the groups (P > .05). Conclusions: The findings indicated no significant differences between the preventive effects of the adhesives used in this in vivo study over 8 weeks.

ABSTRACT Aim To evaluate four different techniques of caries excavation in primary teeth in terms of efficacy, efficiency and pain experienced during the procedure. Materials and methods Sample of 120 teeth from children aged 5 to 9 years were equally divided into 4 groups – Air rotor (group A), Carisolv (group B), Papacarie (group C) and Er:YAG laser (group D). Visual and tactile criteria along with DIAGNOdent pen value was used to evaluate efficacy. Time was recorded to determine efficiency and FLACC scale was used to assess the pain experienced. Results Air rotor and laser were more effective and efficient method whereas laser and CMCR methods were more comfortable methods. Conclusion Laser irradiation and CMCR methods are comparable to conventional methods in terms of effectiveness and are less painful methods. Clinical significance Newer techniques of CMCR and laser irradiation of dentinal caries are minimally invasive methods and are less painful and thus should be more frequently employed in pediatric dentistry.
